Lab 9 introduced me to a more advanced Microsoft Excel. The lab taught us how to more easily find out a linear regression line than if to do it by hand or even a graphing calculator. Because i have been doing linear and other sorts of regressions, the lab didn't teach me anything that i already didnt know about regression lines. But i am glad that i now know how to do it on Excel because i have always had trouble using Excel for other classes' homework. I also now know the basics of excel pretty well so that i could learn more by myself such as some other functions (Standard deviation, etc...) other than the ones we used.
As for data analysis and inductive modeling, like i said before, i have taken a few statistics courses in high school and this lab was just a review of what i already knew just i used excel instead of the STAT and LinReg buttons on the TI-83 calculator.
